sAsH CONSTRUCTION.

Application inea rune 11, 1926. serial No. 115,299.

My invention relates to an impro-ved form of sash construction and more particularly to a sash construction embodying certain new and improved features for supporting the glass carried thereby.

v An object of my invention resides in the provision of means for adjustably carrying or seating the glass between the glass engaging surfaces of the sash members whereby to compensate automatically for varying glass thicknesses and permit a substantially uni form spring pressure aga-inst the glass so as to prevent cracking thereof.

More specifically my invention provides a self adjusting'spring member for exerting a yieldable pressure at the glass engaging surfaces of the sash members. The preferred form of my invention embodies this spring member at the ends of the sash members opposite to the glass engaging surfaces. This location tends to permit the spring member to readily adjust' the sash members, whereby the desired yieldable pressure will be applied against the glass.

Further objects and advantages of my 1nvention will be apparent from the following detailed description when taken in connection with the accompanying drawings, which form a part hereof.

In the drawings:

Figure 1 is a fragmentary perspective view of a corner of a window front embodying my invention;

Fig. 2 is a transverse sectional view taken through the sill and sash members; and

Fig. 3 is a perspective View of a portion of selfsadjusting spring member.

Briefly described the type of sash to which my invention relates usually comprises a sill member 1 and two sash members 2 and 3 for clamping the glass 4 in position. rIhese sash members may be of any desired design, but it is preferable to provide them of sheet metal so as to be slightly resilient and permit their glass engaging surfaces 6 and 7, respectively, yieldably to press against the sides of glass 4. Glass engaging surfaces 6 and 7 are usually provided along the upper edges of sash members 2 and 3. rlhe opposite edges of these sash members 2 and 3 rest upon the surface member of sill member 1 and are preferably so arranged as to permit the water of condensation from the inner surface of glass 4 to drain upon the sill member and flow toward the front edge. From this point the moisture will flow downi provide a gutter 11. A plurality of rain' openings 12 are provided in the slating surface 9 at the base of gutter 11 to permit the water' to drain therethrough into the interior of the sash construction and finally through openings 14 formed in the outer sash member 2. The position ofthese openings in outer sash member 2 lis such as to hide them from view, this being particularly desirable in window front construction, as these openings usually detract from the ornamental appearance. In order that openings 14 will be concealed, an overhanging embodiment 15 may be provided on sash member 2. 1twill be remembered, however, that concealingopenings 14 may be accomplished in many ways.

In order to universally adapt a window front construction to glass of different thicknesses, the sash member should be constructed so as to apply a yieldable pressure against the glass 4 at the glass engaging surfaces 6 and 7. It Ais the purpose of my invention to provide a novel form of means for accomplishing this result. As illustrated in the drawings and disclosed herein, a preferred way of accomplishing this result resides in the provision of a selfadjusting spring member 20 disposed between and engaging the lower inner edges of sash members 2 and 3. `While spring member 20 may assume different forms and accomplish the desired result, it Iis preferable to provide it in the form of a strip having angularly turned edges 21 and 22 adapted to engage corresponding angularly turned edges 23 and 24, respectively, provided on the sash members 2 and 3. Angular edges 21 and 22 are preferably turned inwardly toward each other and the edges 23 and 24 on the sash members 2 and 3 are 'formed accordingly so that the pressure applied by the self-adjusting spring member 20 will be transmitted through the sash members 2 and 3 to the glass engaging surfaces 6 and 7. For the purpose of permitting the sash members 2 and 3 to accommodate glass of different thicknesses, it is preferable to have the spring member 20 self-adjustable, which is accomplished by slightly bowing the spring member, as indi cated in the drawings.

Sash members 2 and 3 may be secured in position in the usual way, say for instance, by screws passing through the outer sash member and into and through, the inner sash member, the inner end of these screws entering the usual wooden block 26 which may be carried on sill member l.

From the foregoing description it will be observed that the water of condensation draining from the inner surface of glass 4f will flow through the openings l2 into the interior of the sash construction from where it will flow outwardly through openings 1l, upon the sill member l. Sill member l is usually made of wood, and consequently, it is desirable to protect it against rotting. I, therefore, provide a metal plate indicated at 28', which `extends rearwardly under the sash construction, and which Ais provided with an upstanding flange 29 to prevent any moisture from contacting with the sill member or wooden block 2G under the sash construction. The metal plate may be formed to cover the drip edge 8.

Itwill be further observed that the selfadjusting spring member 20 will permit the sash members 2 and 3 readily to accommodate glass of different thicknesses, the pressure applied at the glass engaging surfaces being yieldable and in accordance with the thickness of the glass, I find that myinven- "tion has considerable practical utility, and

consequently, do not Iintend to limit myself to the exact form shown herein.

I cla-im: y l. In a sash construction, the combination with sash members having glass engaging surfaces, of a self-adjustable spring member between said sash members at the ends opposite to said glass engaging surfaces for exerting a yieldable pressure at said glass engaging surfaces. f

2. In a sash construction, thel combination with sash members having glass engaging surfaces, of a resilient strip having angularly turned edges adapted to engage cor-v responding angularly turned edges on said sash members, whereby said glass engaging surfaces yieldably press against the glass inserted therebetween.

In witness whereof, I have hereunto subscribed my name.
